1. In the Gram Stain procedure, which component acts as the mordant?

• A. Crystal violet
• B. Methyl alcohol
• C. Iodine
• D. Safranin

Correct answer: C

Rationale: In the Gram Stain procedure, the mordant is Gram's Iodine. The purpose of the mordant is to form a complex with the crystal violet, enhancing its ability to bind to the cell wall. Crystal violet is actually the primary stain used in the Gram Stain procedure to initially color all cells. Methyl alcohol is the decolorizer that removes the crystal violet from certain cell types. Safranin is the counterstain used to stain those cells that did not retain the crystal violet stain after the decolorization step.

2. When providing mouth care to a patient in a coma, what should you do to provide good and safe mouth care?

• A. keep the head of the bed up to prevent aspiration
• B. brush the teeth and rinse the mouth with a cup of water
• C. use a special foam swab to brush only the tongue
• D. use a special foam swab to brush the tongue and teeth

Correct answer: D

Rationale: When providing mouth care to a patient in a coma, it is crucial to use a special foam swab to brush the tongue and teeth. This method helps maintain good oral hygiene for comatose patients. Special foam swabs are designed to effectively clean all areas of the mouth, including the cheeks and tongue, ensuring thorough care. Using water for mouth care in comatose patients can lead to aspiration, so it is important to avoid this practice. Keeping the head of the bed up alone does not prevent aspiration during mouth care for comatose patients, making choice A incorrect. Merely brushing the tongue (choice C) or using a foam swab only on the tongue (choice B) may not provide the comprehensive mouth care necessary for patients in a coma.

3. During an assessment, a nurse asks a patient, "If you had fever and vomiting for 3 days, what would you do?"? Which aspect of the mental status examination is the nurse assessing?

• A. Behavior
• B. Cognition
• C. Affect and mood
• D. Perceptual disturbances

Correct answer: B

Rationale: The nurse is assessing cognition in this scenario. Cognition involves evaluating a patient's judgment and decision-making abilities. By asking the patient what they would do in a specific situation, the nurse aims to determine the patient's cognitive function. A correct response indicating intact cognition would involve a decision like 'Call my doctor.' If the patient suggests inappropriate actions like 'I would stop eating' or 'I would just wait and see what happened,' it would suggest impaired judgment. The other options, behavior, affect and mood, and perceptual disturbances, refer to different aspects of the mental status examination and are not directly assessed through this question.

4. The nurse is reviewing concepts related to one's heritage and beliefs. Which concept refers to an organized system of beliefs concerning the cause, nature, and purpose of the universe?

• A. Culture
• B. Religion
• C. Ethnicity
• D. Spirituality

Correct answer: B

Rationale: Religion refers to an organized system of beliefs concerning the cause, nature, and purpose of the universe, as well as the attendance of regular services. Religion is a shared experience of spirituality or the values, beliefs, and practices into which people are either born or that they may adopt to meet their personal spiritual needs through communal actions, such as religious affiliation, attendance and participation in a religious institution, prayer, or meditation, and religious practices. Culture is a complex phenomenon that includes attitudes, beliefs, self-definitions, norms, roles, and values learned from birth through the processes of language acquisition and socialization. It does not refer to a belief in a divine or superhuman power. Ethnicity pertains to a social group within the social system that claims to possess variable traits, such as a common geographic origin, religion, race, and others. Spirituality is a broad term focused on a connection with something bigger than oneself and a belief in transcendence.

5. Which complication of cardiac catheterization should the nurse monitor for in the initial 24 hours after the procedure?

• A. Angina at rest
• B. Thrombus formation
• C. Dizziness
• D. Falling blood pressure

Correct answer: B

Rationale: Thrombus formation is a critical complication of cardiac catheterization that the nurse should monitor for in the initial 24 hours after the procedure. A thrombus can form in the blood vessels, obstructing blood flow and potentially leading to serious consequences such as embolism or organ ischemia. While angina at rest, dizziness, and falling blood pressure are potential complications following cardiac catheterization, they are not typically associated with the immediate post-procedural period. Monitoring for thrombus formation is essential to ensure early detection and intervention, which can prevent serious complications.
